20oz bottle of LIVE SALTWATER ROTIFERS ,ALSO HAVE LIVE FRESH PHYTOPLANKTON- Mixed in phytoplankton to keep them healthy in transit.
Please note that rotifers are around 130-200 microns in size. Unlike brine shrimp, they can not be easily seen with the naked eye. With the rotifers in a clear container and the water perfectly still, shine a flash light to the side of the container. The rotifers should be visible as tiny specks swimming around when viewed from the surface of the water.
The word rotifer means "wheeled animals" because of the wheel-like feeding appendages which appear to be rotating. Rotifers are microscopic organisms, ranging in size from 100-2500 microns that form one of the most basic links in the aquatic food chain. Specific strains of rotifers are being aquacultured intensively and have been used to raise over 70 species of marine fish and 18 species of crustaceans. As part of the zooplankton they help sustain a microscopic community that supports small fish, and allow them to eat and grow. An interesting fact about rotifers is that they are primarily freshwater or brackish water organisms and are not a natural prey item for marine fish (Hagiwara, A., 1989). However they posses a number of beneficial features that allow us to utilize them for the culture of SW fish larvae. Such benefits are their small size that allows baby fish fry to fit them into their mouths; they have soft outer bodies and are highly digestible. They move slowly and are easily followed and tracked by larvae; they stay suspended in the same water column like the fish fry and as such are in close proximity to the hungry fish larvae. Next, they are readily cultured in large numbers, rapidly reproduce, and when fed phytoplankton become enriched sufficiently to allow fish larvae to grow and develop.
